be worn and insulated adjustment tools must be used when working with control under power. This
product is constructed of materials (plastics, metals, carbon, silicon, etc.) which may be a potential
hazard. Proper shielding, grounding and filtering of this product can reduce the emission of radio fre­quency interference (RFI) which may adversely affect sensitive electronic equipment. If further infor­mation is required on this product, contact the Sales Department. It is the responsibility of the equip­ment manufacturer and individual installer to supply this Safety Warning to the ultimate end user of

III. MOUNTING

Mount the KBRF-300 on a flat surface using the two (2) mounting tabs. (See figure 1, on page 4.)
Be sure unit is not exposed to environmental conditions which will adversely affect its operation
such as water, excessive temperature or metal chips.

IV. WIRING (See figure 2 on page 5)

a) Wire KBRF-300 Filter to control using 1/4” - QD terminals. Wires should be as short as possi-

ble and may have to be shielded with the shield grounded (earthed) at both ends.

b) Wire AC line to filter using 1/4” - QD terminals. Shielded wiring is normally

not necessary for

the AC line. Be sure to connect ground wire to 4 mm ground stud (Earth) on KBRF-300 Filter.

V. RFI/EMI CONSIDERATIONS

a) It may be necessary to shield the motor speed control or mount it in a metal enclosure to

reduce radiated EMI.
